Ballroom Dancing in marikina, antipolo, cainta area

Hi all!
I've been wanting to learn how to dance, but can't find any dance schools nearby. I'm searching though the net so I know that I'm missing on a lot.
I want to learn how to dance, preferably in a "class" environment because I can't afford to hire a D.I. and I don't have the space for dancing at home.
I live in the lower antipolo area so Marikina and Cainta is very accessible to me. Do you know any ballroom dancing classes in those areas, or also, some affordable D.I.s that are willing to go to my area. My sister wants to learn and maybe I could pull a few friends too.
Thanks for all your help :)
